Whakaoti i te 2/3-1/6+7/4-1/2=

$$\frac { 2 } { 3 } - \frac { 1 } { 6 } + \frac { 7 } { 4 } - \frac { 1 } { 2 } =$$

Aromātai

$$\frac{7}{4}=1.75$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 3 me 6 ko 6. Me tahuri \frac{2}{3} me \frac{1}{6} ki te hautau me te tautūnga 6.

$$\frac{4}{6}-\frac{1}{6}+\frac{7}{4}-\frac{1}{2}$$

Tā te mea he rite te tauraro o \frac{4}{6} me \frac{1}{6}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{4-1}{6}+\frac{7}{4}-\frac{1}{2}$$

Tangohia te 1 i te 4, ka 3.

$$\frac{3}{6}+\frac{7}{4}-\frac{1}{2}$$

Whakahekea te hautanga \frac{3}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{1}{2}+\frac{7}{4}-\frac{1}{2}$$

Ko te maha noa iti rawa atu o 2 me 4 ko 4. Me tahuri \frac{1}{2} me \frac{7}{4} ki te hautau me te tautūnga 4.

$$\frac{2}{4}+\frac{7}{4}-\frac{1}{2}$$

Tā te mea he rite te tauraro o \frac{2}{4} me \frac{7}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{2+7}{4}-\frac{1}{2}$$

Tāpirihia te 2 ki te 7, ka 9.

$$\frac{9}{4}-\frac{1}{2}$$

Ko te maha noa iti rawa atu o 4 me 2 ko 4. Me tahuri \frac{9}{4} me \frac{1}{2} ki te hautau me te tautūnga 4.

$$\frac{9}{4}-\frac{2}{4}$$

Tā te mea he rite te tauraro o \frac{9}{4} me \frac{2}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{9-2}{4}$$

Tangohia te 2 i te 9, ka 7.

$$\frac{7}{4}$$

Tauwehe

$$\frac{7}{2 ^ {2}} = 1\frac{3}{4} = 1.75$$
